Yu-Gi-Oh! Duel Links
The Card Trader appears as an NPC in Yu-Gi-Oh! Duel Links upon reaching Stage 7, where he encourages the player to trade Gold and Jewels with him in order to obtain a variety of cards. He also trades plain Gate Keys for colored ones.
The card stock the Card Trader has at hand at any given time is randomized, and he only carries 1 copy of each card he shows to the player. If the player checked his stock, once 8 hours pass, his card stock will change and his Gate Key stock will be refreshed.
Many cards are not possible to be traded for until the player reaches Stage 18.
